Zettai Kunshu! Sayo-sama!

Unable to find a regular job due to the current job market, the protagonist works part-time to make ends meet. It was just like any other day when he was looking at the classifieds and found a job opening for a "master's servant”. What did that even mean? A butler or something? Anyway, there had never been such a job ad before. "The words ""no education or work experience required” sounded too good to be true… When he went for the interview, he was greeted by a young lady... "Are you the one who wants to become my 'pet'?" Isn't that a little different from the job description...?
